1 Claim. 1

Our present invention relates generally to windows, and moreparticularly to an auxiliary window construction embodying aninterchangeable storm and screen sash which may be installed or removedfrom within, and which may be interengaged with the building frame andassembled together in an air-tight association.

In prior combination windows of this general type, many difficultieshave arisen due to the obldow unit which obviates the above and otherobjections and combines the qualities of strength,

long life, easy installation, smooth operation, airtightness, andattractive appearance, as well as eliminating such burdens as heavylifting, sticking, and dirt-trapping.

Another feature of our invention pertains to the novel and enicientchannel strip construction with our novel locking, sealing, and holdingflange, and reinforcing sliding edge element for housing theinterchangeable storm and screen sashes and for adjustable attachment tothe building window frame so that our combination window can be partlyhoused in such frame as to be unobtrusive and, in effect, constituting aweather-stripping construction, and an ornamental feature;

A further feature of our invention resides in 1 the provision of uniquemeans for locking the sashes tightly with the windowsill, after suchsashes have been installed, yet permitting ready and easy removal whenso desired.

A still further object of our invention is to provide means to hold theupper sash from sliding downwardly while the lower sash is beingremoved, thus facilitating removal and preventing injury to theoperator.

Further advantages, features, and details of construction will behereinafter more fully pointed out and claimed.

Referring to the drawings showing a preferred embodiment of ourinvention:

Fig. 1 is a front elevational view showing our combination window ininstalled position;

Fig. 2 is an enlarged cross-sectional view on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged cross-sectional view on the line 3-3 of Fig. 1;

Fig. 4 is an enlarged cross-sectional view, similar to Fig. 3, showing alower sash partly removed; and

Fig. 5 is an enlarged cross-sectional view on the line 5 5 of Fig. 1.

In the drawings, a building window frame of conventional design isshown, having like side sections IIl-I, connecting top section II, and-abottom sill I2. Adapted for association with each side IEI' throughoutthe length thereof and with the top I I between said sides is our novelchannel strip, preferably stamped out of a sheet of aluminum or othersuitable rust-proof material, and bent into desired shape as clearlyshown in Fig. 5, comprising a bottom portion I4, a doubly reinforcedouter side arm I5 extending at right angles vto said portion I4, theouter fold of which portion I5 projects inwardly at approximately aforty-live degree angle to effect a flange I6, which, in turn, is formedwith an attaching surface I1. For purposes of identification, we havedesignated each side-channel strip generally as I3, and the channelstrip across the top as I 8.

A doubly reinforced inner side arm I9 parallels the outer side arm I5throughout the entire top channel I8 and throughout substantially theupper half of each side-channel I3; but along the lower half of eachchannel I3 to permit ready-installation and removal of sashes adapted toslide` therein, said inner arm I9 is clinched laterally against thebottom portion I4, as clearly shown in Fig. 2. I

The channels I3 and I8 are secured to the side frames IQ-Iii and top IIby anysuitable means, such as a plurality of screws 2U driven thru theattaching surface I'I. In this connection, it will be apparent that ournovel channel strips I3 and I8 may be fastened to each frame III and topII, as shown, with the bottom I4 iiush therewith or removed slightlytherefrom and with shims or the like therebetween, when adjustments arenecessary to compensate for dimensional irregularities frequentlyencountered in building frame construction.

It will also .be apparent from the novel design of the iiange I6 and itsattaching surface I'I that our channel strips I3 and I8 are enabled tobe partially housed within the exterior limits of the frames III-4I),thus not only eliminating the bulky outside projections often prevalentin existing combination windows, but also, particularly in View of thedetailed bevel arrangement of said flange I6, in effect adding anattractive appearance to the whole building.

It is believed that our unique channel construction is a distinctimprovement in this art, and

accordingly we wish to claim the same herein broadly.

suitably secured in the bottom portion of the top channel I8 are one ormore leaf springs 22-22 adapted to exert tension against the top frame24 of an upper sash unit 23 when lifted into position, as shown in Fig.3. We have shown the unit 23 as being of the standard type having saidtop frame 24, grooved bottom frame 25, and side frames 26-26 of properdimensions to slide in the channels i3-i3, such four frame membersenclosing a usual glass pane 21.

A lower sash unit 28 is provided having sid frames 29-29, grooved bottomframe 3H and top frame 3| formed with s, tongue 32 to t into saidgrooved frame 25 in weather-tight association, said frames, in turn,supporting as shown a glass pane 34 or, if desired, a Ventilatingscreen. Positioned below said grooved frame 30 and cooperating therewithin weather-tight relation by means ofthe tongue 33 is a toggle apron 35,the lower surface of said apron 35 designed to rest Vupon the windowsill l2 and form a tight joint therewith.

Losely mounted on the sill I2 and secured thereto by loops 35-38 are apair of combination brackets 31h-3l which are positioned adjacent to andadapted to cooperate with said apron 35, functioning in the capacity ofa spring clip or catch 38 when swung into the position shown in Fig'. 3,and acting as an apron support 39 when swung into the position shown inFig. 4.

To facilitate Vthe installation and removal of the lower sash 28, wepreferably attach by means of screws 4l a pair of finger-hooks 40--40 tothe bottoni frame 30, thus `prmfidirag an operator with suitable liftingand pulling means for both purposes.

In order to hold 'the upper sash and window 'from dropping down entirelywhen the lower sash is swung outwardly and removed, we provide anysuitable catch in position as indicated at 50, Fig. 1, to catch theupper sash` whenit is dropped slightly because of its weight and theexpansive action of the springs 22 during the removal `of Athe lowersash.

For this purpose, a spring-pressed plunger may be' tted, as Shown at 50,to Vproject in the path ci the upper sash as the lower une is removed,or any other suitable catch can be manually compressed when it isdesired to lower the upper sash completely 'and swing it inwardly forYwashing, removal, or replacing.

The important feature of our construction, utilizing the toggle apron 35together with the advantages incident to our novel form of channel,

which is, in effect, a. combined channel and weather-stripping element,will be readily appreciated. With the apron 35 swung inwardly andresting on the bevelled surface of the catch 39, the lower window orscreen can be easily adjusted with the tongue 32 in the correspondinggroove in the upper sash, and with the bottom portion tting on the topsurface of the tongue 33 in the apron 35. Thereupon, a slight pressureinwardly lifts both window frames against their own Weight and thetension of the springs 22 by the toggleaction provided by ourconstruction, thereby firmly forcing both sashes and toggle apron incontact and alignment with the respective channels on each side, therebyholds all members under tension of the springs 22 in the topmostchannel. Thus the operator is relieved of the exertion of lifting thesashes, Aboth upper and lower, and forcing the same to slide in thechannels since the simple toggle action aiorded by the pushing in of thebottom sash does the lifting automatically.

We claim:

Interchangeable glass and screen construction of the kind described forassociation with a building Window frame, comprising upper and lowersashes, U-shaped side channels in which the edge portion of said sashesmay slide, the lower part of one ilange of said U -shaped channel beingomitted, said channels being constructed .and

arranged to be partly housed within the building window frame, and withan integral angularly extending bracing flange adapted to be attachedoutside said window frame, spring means in the top channel strip, atoggle apron positioned on the sill of said window frame and havinginterlocking means with the lower sash, swinging catches formed with apredetermined angle on which the toggle apron may rest in position Vtoengage said interlocking means between the toggle and the lower sash,whereby swinging of the lower sash and toggle into vertical alignnientwill raise both sash and toggle into springtensioned engagement with thespring means in the top channel.
